IMPROVEMENT IN DEVICES FOR PITCHING BOATS.

Specification forming part of Letters Patent No. 135,490, dated February4, 1873.

To all whom it may concern:

Be it known that I, WILLIAM H. Brennan- SON, of Stillwater, in thecounty of Washington and State of Minnesota, have invented a new anduseful Improvement in Apparatus for Pitching Boats, of which thefollowing is a specification:

The object of this invention is to provide efficient and convenientmeans for expeditiously pitching the seams of boats and marine vesselsof all kinds, also the seams of floors or platforms when the same are tobe made water-tight and it consists in an apparatus or machine with arevolving wheel and lamp chamber therein, and hollow brush, theconstruction and manner of operation being hereinafter more fullydescribed.

In the accompanying drawing, Figure l is a vertical longitudinal sectiontaken on the line as w of Fig. 2. Fig. 2 is a top view.

Similar letters of reference indicate corresponding parts.

A is a rectangular-shaped vessel, open at the top, preferably with acircular bottom, B. Beneath the bottom is the lamp-chamber O. O is thelamp. D is a sliding shutter on the side of the lamp-ch amber. Thisshutter closes the aperture through which the lamp is introduced. E isthe handle. F is a wheel which revolves in the vesselA by means of theshaft G and journal-boxes H H. This wheel is made in two parts, so thata rim of cotton, I, is confined between the parts and forms itsperiphery. The diameter of the wheel is such that it runs near thebottom of the vessel. The pitch is kept in a liquid state in the vesselA by means of the lamp in the chamber 0. J is a discharge-tube or spoutin two parts,

J being curved and removable. On each side by the slides L on the insideof the vessel. m is a cap, by which the front tube J is closed. N is abrush with a hollow handle or stem. The socket of this brush fits eitherof the three tubes mentioned. When either of the side tubes are used thefront tube J is closed 3y the cap after taking off the curved portion Inusing the article it is held by the handle and pushed along with thebrush N in the seam. If it is the deck of the vessel, the brush isattached to the curved spout or tube J. If the side of the boat is to bepitched, the spout J is closed, (J being removed,) and the brush isattached to one of the side tubes K, the other side tube being closed bythe slide L. If it is the bottom of the vessel, then the wheel F isemployed, and the machine is run along with the cotton-rim I in the seamwhilethe wheel revolves in the pitch and carries the pitch to the568.111.;

It will be seen that the machine is adapted to all parts of the vessel,and that the operation of pitching a vessel may be performed with easeand dispatch.

Having thus described my invention, I claim as new and desire to secureby Letters Patcut- The brush N, having hollow perforated handle,combined with discharge-tubes J K K of pitch-vessel A, as and for thepurpose described.
